Definitions

  • the present invention relates to a prosthesis, in particular a joint prosthesis, e.g., a hip prosthesis (total or cephalic).
  • a joint prosthesis e.g., a hip prosthesis (total or cephalic).
  • European Published Patent Application No. 85 147 has already proposed a hip joint prosthesis for implanting in the proximal end of the femur, which prosthesis is made up of two independent parts, namely, a main body or spatula, and a wedge-shaped side part.
  • the side part is intended to slide in a guide profile provided on the narrow side face of the spatula.
  • the reference proposes providing a series of side parts of different thicknesses, each of which side parts may be combined with a common spatula in order to cover a range of prosthesis widths.
  • This arrangement is essentially intended to enable the prosthesis to be placed at a specified height in the end of the femur.
  • the prosthesis is implanted in two stages:
  • the main body of the prosthesis and the wedge-shaped side part are thus two initially separate items which are brought together solely during prosthesis implantation. These items are never genuinely fixed relative to each other, and as a result they are difficult for the surgeon to handle both before and during implantation, and may give rise to inaccuracies.
  • forces are applied to the prosthesis (and these forces may be very high, and in various different directions), there is a risk of the two parts working loose relative to each other, and thus of the prosthesis assembly working loose from the bone.
  • Preferred embodiments of the present invention remedy these drawbacks by providing a prosthesis of the above-described type in which handling is facilitated, both before and during implantation, and which is securely and durably retained by the bone after implantation.
  • the present invention provides a prosthesis kit comprising an elongate prosthesis body and a series of modular strips of different thicknesses which are suitable for being combined with said body to constitute assemblies of different widths, wherein each of said modular strips has a longitudinally extending dovetail section edge which is suitable for interfitting in a complementary dovetail section provided on a side of said elongated body, said interfitting dovetail sections ensuring that the assembled body and strip are mutually fixed against relative sideways displacement.
  • the selected strip is fitted to the main body prior to the prosthesis being implanted, thereby considerably facilitating manipulation of the assembly during an operation. After the assembly has been put into place, it is impossible for the two parts thereof to work loose relative to each other in a sideways direction.
  • each strip has a substantially constant thickness from end to end, thereby providing good force distribution between bone tissue and the prosthesis assembly, and hence further reducing the risks of the prosthesis working loose from the bone.
  • said dovetail sections taper slightly from end to end.
  • the dovetail sections can thus be wedged together while the parts are being assembled.
  • the taper it is advantageous for the taper to be such that friction forces between the bone tissue and the walls of the strip as the prosthesis is being inserted into the medullary canal tend to enhance the wedging effect, since this will result in the implanted two-part prosthesis acting as a single solid item with relative displacement between the parts being prevented both laterally and longitudinally.
  • the male or tongue dovetail section is on the modular strip
  • the female or groove dovetail section is on the prosthesis body
  • the wider end of both sections should to be the distal end, with the selected strip being slid into the prosthesis body from the distal end, i.e., the end which will be the bottom end when the patient is standing upright.
  • FIGS. 1 and 2 are a front view and a right-hand side view respectively of the prosthesis body on its own;
  • FIG. 3 is a horizontal section on a plane III--III of FIG. 1;
  • FIG. 4 is a front view of a prosthesis body to which a thin modular strip has been fixed
  • FIG. 5 is a horizontal section on a plane V--V of FIG. 4;
  • FIGS. 6 and 8 are front views of modular strips of average and of large thickness, respectively.
  • FIGS. 7 and 9 are sections analogous to FIG. 5, in which the prosthesis assembly includes the modular strip of FIGS. 6 and 8, respectively.
  • the prosthesis body designated by reference 1 in FIGS. 1 to 3 is a femur prosthesis of a generally conventional type in the form of an elongate flat rod 11, a collar 14, and a Morse taper cone 10 for receiving a femur head in conventional manner.
  • the outside edge 12 of the body 1 is rectilinear in shape and has a longitudinally extending dovetail-section groove 13 formed therein.
  • the width d of this groove tapers very slightly when going from the distal end (at the bottom in FIGS. 1 and 2) towards the proximal end (at the top in the figures).
  • the width d 1 of the groove at its distal end may be about 4.5 mm, while its width d 2 at the proximal end may be about 4 mm.
  • the groove 13 opens out at both ends of the body 1.
  • FIGS. 4, 6, and 8 show three modular strips, each of which may be fitted to the above-described prosthesis body 1.
  • the figures show a thin strip 2a having a thickness Ea, a medium strip 2b having a thickness Eb, and a thick strip 2c having a thickness Ec.
  • Each of the strips is of substantially constant thickness from one end to the other. However, the outside faces of the ends themselves are curved in order to meld progressively with the corresponding ends of the prosthesis body.
  • Each strip 2a, 2b, 2c, . . . in accordance with the invention has an identical inside edge 20 with a dovetail-section tongue projecting therefrom, which tongue is complementary to the groove 13 in the body 1.
  • FIG. 4 shows the strip 2a in place on the body 1.
  • the strip is put into place by displacing it longitudinally upwardly relative to the body because of the upwardly tapering width d of the dovetail.
  • the total width of the prosthesis constituted by the prosthesis body 1 and the strip 2a is designated D a and may be 15 mm, for example, at the level represented by plane V--V.
  • the resulting overall thickness D b is equal to 20 mm, and similarly if the thick strip 2c is used, the overall thickness D c is equal to 25 mm.
  • the advantage of the present invention stems directly from the above explanation.
  • the surgeon selects one of the available strips in the series, fixes the strip to the prosthesis body, and then places the prosthesis assembly in the medullary canal as though the prosthesis were a conventional unitary prosthesis.
  • the prosthesis may be put into place either with cement or without cement. If no cement is used, it may be desirable to provide roughnesses such as grooves, ribs, or knurling at the top of the prosthesis body when it is initially manufactured, thereby improving prosthesis retention in the bone tissue.
  • the invention covers the situation where the male dovetail tongue is provided on the prosthesis body and complementary female dovetail grooves are provided on each of the modular strips.
  • the invention is applicable to prosthesis other than hip prosthesis, and in particular to shoulder or knee prostheses
